been hearing a lot of instability issues with stock suspension setup for these specific year make/model. i'll be riding my new gsx600rr with stock suspension for a few months....so i'd like to optimize it as much as possible.

do you have your forks recessed into the triples. flush or how many mm in do you have em? do you have fork cap extenders also? did you shim the rear shock to raise the rear also?

I have my forks 5mm sunk into the triples and the rearend is pretty low using a Penske triple clicker running Dunlop D211's. I rode on stock suspension with Michelin Power Race's and had no problems whatsoever.

yeah, remember seeing your forks sunk into the triples and said to myself....DAMMNNNNN

now i see why you did that....considering what i've been hearing about the gsxr oem geometry setup.

Well, I was on an 01 R6 with LE forks and Penske triple that was set up by refreshed and tuned by Jim Cambora. I got my 06 GSXR750 with stock fork valves with .90 springs with a Penske double. My forks have not be lowered through the triples yet. I'm currently running Dunlop 211's with this set up. I just haven't had the time to take the bike to Jim for a refresh or setup for the tires. However, with that said I've shaved a solid 5 seconds off my lap times with this bike compared to last year. Can't wait to get it tuned and some new valves in there. I'm not the fastest novice but I do run respectable times 1:55-56 at TWS (Texas World Speedway) and 1:25-36 at Cresson and 1:29 at OHR. I've had 4 different track bikes, two R6's, 02 GSXR600, and 06 GSXR750. I'm very happy with the 06 750 as it stands right now, it can only get better with a few extra suspension parts/tuning.

Hey guys please excuse my ignorance, but I’ve always heard to raise your fork tubes through the triple to help turn in which it does for sure. My last track day a racer told me to lower the forks to make them flush with the triple saying I will have more suspension travel. He talked about the extenders to etc.. So what the low down on this? If you lower the forks flush will you have change the compression or rebound any? Didn’t mean to jack the thread in any way, but figured I’d ask since you guys were talking about it and are racers.
Thanks.

Both Derek Wagnon & Brandon Spradling run the BT003's and have extended forks and recessed 5-6 mm's. I'd call Jim Cambora or Patrick at Motorcycles Unlimited and see whats up. The geometry works, the numbers don't sound right, but they both seem to be hauling . They both have newer GSXR 600's. Derek has a 750 as well.
